Application May 24, 1954, Serial No. 431,667

1 Claim. (Cl. 1--101) This invention relates to new and usefulimprovements in a stapling machine.

It is an object of the invention to provide a stapling machine for usein stapling small packages to a cardboard sheet.

In marketing spices and the like, which are packaged in small,transparent bags, it is customary to attach a prescribed number ofpackages to a cardboard display card for the merchant to hang on a rackand which packages the customers easily remove from the card. Toaccomplish this, the packages are usually stapled to the cardboard, andthe method of stapling is usually a manual manipulation of a staplingmachine, which requires placing the card and package at an angle in themachine and manipulating a foot pedal to fasten the staple. Itis anobject of this invention to provide a machine that will electricallyoperate the device and that will permit rapid fastening of the packagesto the cardboard display card.

With the above and other objects in view, the invention has relation tocertain novel features of operation and construction more particularlydefined in the following specifications and illustrated in theaccompanying drawings, wherein:

Figure 1 is a top plan view of the device.

Figure 2 is a front elevational view, and

Figure 3 is a diagrammatic sketch of the wiring.

Referring now more particularly to the drawings, the numeral 1designates a conventional stapler mounted on 'ice a suitable base as 2.A housing 3 encloses an electrically operated actuator arm 4, which isactuated by a solenoid as 5. A suitable insulating pad 6, such as spongerubber, is mounted between the housing 3 and the base 2.

Mounted on the base 2 adjacent the forward end of the stapling device 1is a contact switch 7. Whena cardboard backing, as 8, is insertedbetween the jaws of the stapling device 1, and the package 9 to bestapled thereon is placed in the desired position on the cardboardbacking, the cardboard backing it tilted, pressing on the switch 7, andcompleting a circuit through the solenoid 5, causing the actuating arm 4to move downwardly, pressing the plunger 11 of the stapling devicedownwardly, and fixing a staple in the package and backing board. Asuitable rubber bumper, as 12, may be mounted between the top of theplunger 11 and the end of the actuating arm 4, promoting silentoperating of the device.

The construction above set out permits rapid and accurate assembly of adisplay card with the desired number of packages stapled thereto in aminimum of time and with a minimum of effort.

While the foregoing is considered a preferred form of the invention, itis by way of illustration only, the broad principle of the inventionbeing defined by the appended claim.

What I claim is:

In a stapling device, a staple dispensing means having elongated jaws,an actuating device extending outwardly and rearwardly from said jawsand in operative connection with said staple dispensing means, anelectrically operated solenoid in said actuating device, a pressuresensitive switch adjacent said jaws, means for opening and closing saidswitch upon tilting of a display card inserted between the said jaws.
